build-system/pyproject: Use python-sans-pip-wrapper as default-python.

Also adds python-setuptools and python-wheel to relevant packages,
either to native-inputs or to propagated inputs if the pkg_resources
Python module is loaded at runtime.

* guix/build-system/pyproject.scm (default-python): Default to
python-sans-pip-wrapper.
